Enhancing colour for LRGB images

This routine was given to me by a quite good imager in the south of france :tongue:

If you are a bit short of colour and the image looks washed out when you add the L, try this;

Add L to RGB in Ps at about 30% opacity, blend mode Luminance. Flatten. Increase saturation. Blur/noise reduce/despeckle.

Re-apply the L to this semi-L/RGB image and try 60% this time. Again blur and noise reduce it and flatten, and increase saturation. Now try a third iteration of L. All the time the layer you are calling RGB is getting a little more L in it but you are noise reducing it and increasing saturation. Eventually there's a good chance that it will take a heavy application of L.

Another one take your RGB into Lab colour mode (Image-Mode) and split channels. Go to Image, Adjustments, Brightness and Contrast (the only time you will use this numpty tool!!) and, on the a channel and the b channel only, increase contrast by a whopping 30. Recombine the channels and reconvert to RGB.
